Colored timestamp

allanm77 — Sun, 17 Jun 2012 05:17:20 GMT

Hi I have the following script snippet which is used to ssh to a host and tail the logs , I need the timestamps to be colored (for the entries which are from today if possible) -

while read HST SERVER ENV PORT
do
    [ $(echo ${SERVER}) != ${WHATSERVER} ] && continue
   ssh -n ${HST} "tail -500 /Logs/${SERVER}_${HST%%.foobar.com}_${PORT}"
   ssh -n ${HST} "ls -ltr /Logs/${SERVER}_${HST%%.foobar.com}_${PORT}"
done < ${HSTFILE}

Logs are of following format-

>>>>> | dtm=2012-05-03 15:00:00.295 PDT |

Thanks,

Allan.

You might want to combine the two ssh commands into one:

ssh -n ${HST} "tail -500 /Logs/${SERVER}_${HST%%.foobar.com}_${PORT} ; \

ls -ltr /Logs/${SERVER}_${HST%%.foobar.com}_${PORT}"

>Logs are of following format: >>>>> | dtm=2012-05-03 15:00:00.295 PDT |

You could use sed to insert the escape sequences:

done < ${HSTFILE} | sed -e 's/$.*dtm=$$'$(date +"%Y-%m-%d")'$$.*$$/\1ESC-start\2ESC-stop\3/'

Where ESC-start & ESC-stop are the appropriate escape sequences for your color. You may want to use tput(1) to generate them.

Hi Dennis,

For the sed statement I am getting -

sed -e '$.*dtm=$$'$(date +"%Y-%m-%d")'$$.*$$/\1`tput smso`\2`tput rmso`\3/'

sed: 1: "$.*dtm=$\(2012-06-18\ ...": unterminated regular expression

Thanks,

Allan.

Oops, I forgot the "s" command. See my post above.

Trying to use tput(1) directly doesn't work if it contains a "&", a sed special.

This is what I had to do:

# Need to use echo to add a newline since sed won't work on non-text files. Then remove the newline.

# Need to quote each "&" since special to sed.

SMSO=$(echo $(tput smso) | sed -e 's/\&/\\\&/g' -e 's/\\n//')
RMSO=$(echo $(tput rmso) | sed -e 's/\&/\\\&/g' -e 's/\\n//')

# while loop here

... sed -e 's/$.*dtm=$$'"$(date +"%Y-%m-%d")"'$$.*$$/\1'"$SMSO"'\2'"$RMSO"'\3/'

Reopening the thread.

Thanks to Dennis, I do get the date in colored , was wondering if we can get ERROR (all caps) also colored if it occurs in the logs.

Sample output which has ERROR.

>>>>> | dtm=2012-08-19 09:27:28.344 PDT | level=ERROR

Thanks,

Allan.

If you don't care which date has the "ERROR" string:

sed -e ... -e "s/ERROR/${SMSO}ERROR${RMSO}/g"
